Given all of this, it could be argued that to minimise aspect ratio errors across the full range of standards and display devices, the absolute "best" that can be done is to encode at 704x576 or 704x480 (never 720, which is unpredictable on PCs vs TVs), and to treat that as the full active area.
Agree.

Software dvd players (like PowerDVD) show 720x576, 720x480MPEG-2 pictures with wrong aspect ratio because they use it as active area. Don't trust them!
But 704x576, 704x480 handling is ok.

Not enough: A lot of new movies are encoded with this issue.
(All Harry Potters use 720x576 = 16:9). And so only the software players show the right AR on PC.
And look at the circle calibration tool on dvd Ratatouille, circle 720x576 PAL - same issue!
